7.6.1.6 Debugging

  • -g level (Debugging level)

    • -g1

      It produces minimal information, enough for making back-traces in parts of the program that you don't plan to debug. This includes descriptions of functions and external variables but no information about local variables and no line numbers.

    • -g2

      It is the default debugging level.

    • -g3

      It includes extra information, such as all the macro definitions present in the program. Some debuggers support macro expansion when you use -g3.
